Petrobras reinjected 14.2 million tons of CO2 into the Santos Basin pre-salt reservoirs last year, surpassing the volume of 13 million tCO2 reinjected in 2023. In addition to being a pioneer in ultra-deep waters, the program is the largest in operation in the world, considering the amount of CO2 reinjected annually. According to the latest report by the Global CCS Institute (GCCSI, 2024), the annual injection capacity of CCUS (carbon capture, utilization and storage) projects in operation worldwide reached 51 million tCO2 in 2024. Thus, injection into pre-salt reservoirs corresponds to more than a quarter (28%) of the global capacity reported for the year 2024. Pioneering technologies contributed to a cumulative injection volume of 67.9 million tons of CO2 between 2008 and 2024.
Currently, 22 FPSOs (platforms that produce and store oil) operating in the Santos Basin pre-salt are equipped with systems for capturing and reinjecting CO2. The application of this technology in the ultra-deepwater environment is a pioneer in the world and, while reducing CO2 emissions, optimizes oil recovery (CCUS-EOR).
